thanks, OK so in the ending song "still alive" there is a line "There is research to be done ON the pople who are still alive im geussing this could be a hint to portal three being a game where you play as another test subject and due to the fact that weel in the start you see all the other "boxes destroyed if Glados knows that everyone is still alive don't you think that she would systematically go through all the test subjects . starting with Chell due to Rattmans editing skills so im geussing that maybe you might adventurally play as Rattman escaping and then finding chell and wheatley i leave you one question if Cave Johnson got rocks from the moon then i think they might have something on the moon like a test in space making me think that you might be able to shoot a portal again at the moon and rescue Wheatley to save aperture as Wheatley has learnt his lesson as he says "if i could take it all back and im not just saying that cause im stuck in spaceyou know if i was ever to see her again , do you know what i'd say?id say, im sorry . sincerely . im sorry i was bossy and monstrous and im genuinely sorry The end"but it isn't the end nope portal 3 will come i beleive it will come Thank-you
